JAMA Neurol:羟丁酸钠可改善帕金森患者白天过度嗜睡和夜间睡眠障碍

2017-11-09 zhangfan MedSci原创

睡眠障碍紊乱是一种常见的帕金森非运动失调症状,治疗方案十分有限。近日研究人员考察了发作性嗜睡病一线用药--羟丁酸钠对帕金森患者白天过度嗜睡(EDS)和夜间睡眠睡眠障碍的疗效和安全性。本次IIa临床研究在瑞士进行。12名Epworth睡眠得分>10的PD患者参与。参与者随机接受羟丁酸钠或安慰剂,研究过程中1人因不良事件退出,11人完成最终研究。患者在睡前2.5-4小时服用3或9g药物,持续6周

睡眠障碍紊乱是一种常见的帕金森非运动失调症状,治疗方案十分有限。近日研究人员考察了发作性嗜睡病一线用药--羟丁酸钠对帕金森患者白天过度嗜睡(EDS)和夜间睡眠睡眠障碍的疗效和安全性。

本次IIa临床研究在瑞士进行。12名Epworth睡眠得分>10的PD患者参与。参与者随机接受羟丁酸钠或安慰剂,研究过程中1人因不良事件退出,11人完成最终研究。患者在睡前2.5-4小时服用3或9g药物,持续6周,之后间隔2-4周。研究的主要终点是在多次睡眠潜伏期通过平均睡眠潜伏期电生理测量评估的客观EDS症状变化。次要终点包括主观EDS、睡眠质量以及客观夜间睡眠。

12名患者中,男性患者10人,平均年龄62岁,患病时间8.4年。研究发现,服用羟丁酸钠可主 (平均睡眠潜伏期延长2.9分钟) 客(ESS 得分减少4.2分)观上改善患者EDS症状。67%的患者表现出电生理学积极的治疗反应。羟丁酸钠显著提高睡眠质量和客观慢波睡眠时间 (+72.7分钟)。羟丁酸钠耐受性良好,2名患者出现阻塞性睡眠呼吸暂停,1名患者出现过深眠状态。

研究认为,羟丁酸钠可改善帕金森患者白天过度嗜睡和夜间睡眠障碍症状,该试验结果需要大规模长期临床试验的验证。
